The following reply was made to PR kern/71771; it has been noted by GNATS. From: "Michel Gravey" <michel.gravey@7ici.biz> To: "Michel Gravey" <michel.gravey@7ici.biz> Cc: <freebsd-gnats-submit@FreeBSD.org> Subject: Re: kern/71771: Hang during heavy load with amr raid controller (466 series / dell perc 2 SC) Date: Thu, 16 Sep 2004 11:31:18 +0200 The hang still occurs with a kernel just compiled with -O. So I really need the patch I submitted. Maybe not the good way but it works fine for me. I can test other patches if you have any.
